Years ago, someone with an IQ of 70 decided that all homes needed a BACKflow prevent er, because, it COULD BE? The hose with an insecticide sprayer may back flow stuff into the house water???

Well there would have to be no house water pressure and there would have to be an elevation change or a pump to get the contaminated water back into the house ?????????? On two houses, I have removed and saved them, then able to install at the hose sale, if code wants it. Good luck.
